Re: LF: Dongel-SDR on LF?

Thanks Victor, LF,

What a crazy world this is! I feel like an oldtimer when seeing all that 
new stuff. The technical world accelerates itselfe more and more.
I just found this video, please see

Coincidentally i had to renew my mobile phone contract some days ago. I 
also had to (wanted to) buy a new mobile phone. Now i have mobile 
internet! Good for /p experiments and remote controlling the LF TX!. It 
is a smartphone (Samsung Galaxy S3) which is able to work in combination 
with such a RTL dongle. So if that means i can build a portable SDR for 
LF and MF (and HF)... Unbelivable!
I will try all that new world stuff and report here.
